AIRLACCELERATOR.

Application filed December 28, 1912. Serial No. 739,095.

To all whom it may concern:

Be it known that I, JOHN W. FUDGE, a citizen of the United States, fresidingf at Marion, in the county of Grant and State of Indiana-,have invented anew and useful"y Air-Accelerator, ofi-Which the following' is a specification.

The present invention appertains to what '-may be termedjan air accelerator, or to an ills ira-tor .for introducingvheated air into t intake manifold yof an internal combustionlengine. l

`Thisinvention contemplates the produc- :tion lof an attachment for various internal 'combustion engines, such as automobile, ma-

yrine, and-stationary engines, in order to, supplyair tothe 'intake manifeld andin o rder that the air supplied to the intake manifold maybe -throttled according to the throttling of the mixture'proceedingjfromy the carbureter. It is a. further object of the present inven- -tion to provide an air inlet'valvevvhich may be operatively connected Vto any suitable part of.l the throttling mechanism for the' combustible 1riixture,and Which may be connected to the intake manifold through the medium of a tube orv pipe, a portion of Whichmay be disposedfcontiguous to orV coiled around the exhaust' manifoldv so as to heat the air supplied to the intake manifold.

lt is also lthe object ofthe present-invention to provide an air valve which shall be adjustable so as to lregulate the passage therethrough when the valve is open, thus permitting the auxiliary supply of. air fin- Ytroduced into the intake manifold to be regulated to alnicety.

The present invention also aims .to intro duce 'the auxiliary supply of air Vto the intake manifold in such manner as to break up the mixture` passing through the intake ymanifold from the carbureter, the -auxiliary supply of air. being drawn into the intake manifold by the suction created by the pist0n or pistons and commingling with the Amixture proceeding from the carbureter so as to provide a final mixture of high quality or efficiency. I

The invention has for a further object. to improve generally and to increase'the utility ofdevices of that character to Which the present invention appertains.

To the above and other ends, which-will appearas theI description proceeds, the in" speciacati'o'nof tettersrft. i Patented Jan. 19, 1915.

vention resides in the combination and `ar-` rangement of parts andein the details of construction hereinafter described and claimed, it .beingum'derstood that changes in the' precise embodiment of invention herein' ldisclosedlean be made Within the scope of Whatisi laimed Without departing from the spirit` of the invention.

g'ilhe Vvinvention is illustrated in its prei is afragmental plan View of the attachment.

Fig. 3 is ai vertical, central section of the laiiuvalve.-#Fig 4 is a sectionalview on the line 4-4 of Fig. 3. Fig 5' is a fragmental Which is attachable to the intake manifoldV `for introducing the auxiliary supply of'air gthereinto.

Referring specifically to the drawings, the numeral 7; designates .the intake manifold which extends fromthec'a-rbureter 8 to the cylindersgthe'-mixture proceeding from the carbureterfabeing controlled by the throttle lever 9.. ljothe'throttle lever 9 is connected thethrottlerod 10, Which'in turn, is connected to a.. suitable lever 11 that is adapted to be. actuated by the' operator in a manner Well known fin the art. 4'lhe numeral 12`designates the exhaust manifold' orvconduit. The forexv ing parts may be of any prevailinggstyles, it being understood that the pres'- device is applicable to various motors or internal combustion engines.

The present attachment embodies in its essentials, an air valve 13 actuated bythe throttling rod 10 or any other part' ofthe detail. Fig. 6 is a plan view of the nozzle throttling mechanism for the mixture pass-i,

4acconn'nodate a Wrench or other implement.

The cup and its cap form a body or frame for the valve. A nipple 18 Adepends from thebo'ss 17, and the'duct or vent 19 of the nipple extendsthrough the boss. 17 to the bottom of the cup, the bottom of the cup being 'provided with a socket or counterbore 20 at the inner end of the duct. A tu-.

bular member or plug socket 21 has .its lower end seated or secured within the socket 20, and is provided with an opening or port 22 in one side. A circular plug or spigot 23, fits snugly within the tubularmember 21 and is provided with a down.

' wardly opening passag 24 and a lateral port 25 leading'from the passage'24 andadapted to be brought into and out of registration with the opening 22. The cup is provided with a pair of diametrically opposite inlet aperturesor openings 26l adjacent its lower end or bottom. Thev plug 23 is also provided with the reduced stem 27 projecting from its upper end and formin a shoulder 28, a washer 29. being dis ose on the stem 27 and seating on the Shou der 28. The coiled wire sprin 30surrounds the stem 27 and is co1n pressl ly disposed between the washer 29 and the cap 16 soas to give a downward tension to the plug23.l The stem 27 passes' through the cap 16,'the capbeing provided with an'upstanding collar or boss 31 embracing the stem loosely, and a hand nut 32 being screw-threaded on the stem 27 to seat on the collar or boss 31. The nut 32 carries a set screw 33 -for maintaining it in position. In order to operatively connect the air vvalve to the throttling'mechanism the lever' to rotate the plug 23 as the throttling mechanism is adjusted. It is also apparent, that the lever 34 may be so adjusted relative to the plug 23, and that the cup 15 may he properly adjusted relative to the plug, in' order that when the plug is rotated ldue toA the movement of the throttling mechanism, the port 25 will be brought into and out-f registration with the opening 2,2. 'iv hns, when the throttlin mechanism is advanced,

' the port 25 should e gradually brought into registration with the opening- 22, and con# versely, when the throttling mechanism is retracted, the port 25 should be brought out of registrationwith the opening 22 so as to close the air valve. .l

The end of thepipe or tube 14 is connected to the nipple 18 through the medium of an elbow 37, the pipe 14 being connected to one arm of the elbow and the nipple 18 being screw-threaded into the other arm of the elbow.. A portion of the pipe 14 extends contiguous to or is coiled around the exhaust conduit' or manifold 12, as indicated at 14.and the other end of the pipe 14 is connected to a valve 38, -which in turn'is connectedto the injector` nozzle 39. This nozzle 39 isV in the form of an elbow, although it may be otherwise constructed, and has the nipple 40 projecting from one arm which is adapted to be screw-threaded into the intake manifold, the nipple being provided with a plurality of outlet apertures or perforations 41.

attached'to the nozzle 39 and the nipple 18 of the air valve, after the pipe has-been suitably coiled around the exhaust manifold or otherwise extended in a contiguous. rela-- tiontherewith, and after the nozzle 39 has been engaged to the intake manifold.

In order to support the air valve from a suitable part of the motor, or any suitable part adjoining the motor, an arm 42 em-A braces-the -nipple 18 at one end and'is vclamped between the boss 17 andthe elbow 37, the .arm 42 being provided with the longitudinal open slot 43. A base plate 44 is providedwith an ear 45 overlapping the Thus, it will be evident i .that the ends of the pipe14 may be readily arm 42, a bolt or other clamping member 46 p 'being carried by the .ear' 45 and'engaging through the slot 43 so? as to clamp the arm 42V and ear. together. Thus, the arm 42 may ybe positioned atany angle about lthe air valve, and the base 'plate' 44 may be adjusted longitudinally and angularly relative to the arm 42, in` order thatl the base plate may Abe securedto any suitable part adjoining the air valve so as to eiectively maintain the air valve in position. This adjustable bracket for the airA valve pervmits the air valve lto be held in any vlocality or point adjacent the motor, and it will also be manifest that the link 35 may be connected to various parts of various throttling mechanisms kand that the nozzle 39 'may be readily engaged to variousintake manifolds so that'the present attachment may he applied to various internal combustion engines with equal propriety, the present device being somewhat elastic in construction. l

In operation, it will be noted from the `foregoing, that as the mixture supplied to the intake manifold is throttled, .the air valve will be correspondingly throttled, so as to `admit an auxiliary or supplemental supply of air into the intake manifold. The

air is admitted into the cup or receptacle 15 Athrough the apertures 26, from whence it is admitted to the pipe 14 through the ports 22 and 25 as they are brought into registration. The pipe 14 running .contiguous to or coiled around the exhaust manifold or conduit causes the auxiliary supply of air to be heat ed in order that when it is introduced into the intake manifold, it will properly commmgle with the mixture proceeding from the carbureter. The auxiliary supply of air being dlschar'ged from the apertures of the nozzle, causes the mixture proceeding from the carbureter to be broken up still liner Yso and is accomplished bythe carbureter, the

*auxiliary supply of air commingling and combining with the mixture to provide a .final mixture ofhigh quality or eflicieney.

This eXtra supply of air tothe mixture 2livens the mixture, or increases the' efliciency. of the combustion of thel fuel, in order that the same amount of Work is performed' with a smaller quantity of fuel, or in order 'that an eXtra or increased amount of Work is performed With the same amount of fuel, as heretofore.

As above indicated, the auxiliary air supply is drawn. into the intake manifold due to the suction created by the piston or pistons, and in order to adjust the air valve for various motors, or in order to properly tune the device, the plug 23 may be adjusted longitudinally by screwing the nut 32 in either direction, so as .to either raise the-plug or .permit same to be forced downwardly through the action of the spring 30. Accordingly, when the plug 28, is permitted to be depressedislightly,.the port 25 of the plug Will not fully register or coincide with the opening 2Q, as seen in F ig. 5, and as a result.. when the air valve is open, a smaller quantity of air is permitted to How therethrough. Thus, by the adjustment of the nut 32, it will enable the operator to permit .theproperamount vor proportion o'f air to be admitted into the' -intake manifold for accomplishing the result desired. Thus, the supply ofi-air into the intake manifold or conduit-,may be made consistent With the g quality of 'the mixture proceeding from the carbureter, so that the resulting mixture Will be of maximum efficiency.

The entire auxiliary air supply-may be cut off, Whenever itis so desired, by means of the valve 38, Without any injurious effeet to the attachment, and Without impairis claimed as new is .1'.
